A tool device (4) for connecting a plastic pipe or composite metal/plastic pipe to a fitting by means of a sliding sleeve or compression sleeve, including:
- a housing;
- a flaring device for flaring the ends of the plastic pipe or composite metal/plastic pipe;
- a sliding device for sliding the sliding sleeve on or a pressing device for pressing the compression sleeve on;
- and
- a mechanically operable drive element which can be switched to drive the flaring device 94 or to drive the sliding device or pressing device, wherein
- the flaring device includes a first piston-cylinder unit, whose working piston has a piston axis and which has an inner end and an end oriented away from the tool device, and the sliding device or pressing device includes a second piston-cylinder unit, whose working piston has a second piston axis and which has an inner end and an end oriented away from the tool device;
- the piston axes extend parallel to each other and a perpendicular projection of the inner end of the flaring device into the piston axis of the sliding device or pressing device lies between the inner end of the sliding device or pressing device and the end oriented away from the tool device and/or a perpendicular projection of the inner end of the sliding device or pressing device onto the piston axis of the flaring device lies between the inner end of the flaring device and the end oriented away from the tool device.
